Abstract
The near-threshold corrosion fatigue crack propagation behavior of Mil S-24645 HSLA steel, its weld metal and heat-affected zone have been studied in simulated marine environments. Tests were conducted in air and ASTMseawater, at both the free corrosion potential and − 1.0 V (SCE), using a frequency of 0.2 Hz and a stress ratio, R = 0.1. The results were compared with previous data for Mil S-24645 and ASTM A 710 steel tested at frequencies of 10 and 2 Hz. The influence of frequency, microstructure, and cathodic protection on crack closure contributions in the nearthreshold regime will be discussed.
